Correct. Only for sedan rear.

That is an older picture with 30mm? flares, the new design I believe is 50mm (2 inches on each side) which is massive. You can run 10.5j/11j with 3XX series tire! Or you can run very low offset wheel with at least 265/275.

I mean most of the popular RWD (M3,370z etc) cars come with large fenders from the factory but now you can have that plus a little more to play with.

Easiest way to visual this is by looking at your factory widened C63 front fenders and imagining a stagger type flare for the rear. It equals out the cars natural body line. MB designed the C63 W204 with good front fenders but the rears are an illusion because the outline of the flare is there without actual flare.

Also the most aggressive width/offset on stock rolled C63 fender is 18 x 9.5j +25 with a 235/40, but that was on air suspension. I would imagine 18 x 9 +40 would be a breeze. But this all depends how your ride height it set up. Factory front C63 fenders tend to snag when you are too low and/ or run too big of a tire. I will be running close to black series OEM sizing 9 +25 /+ 30 on factory front fenders.

Now I'm glad I created this thread. Progress is what we need! Too many failed "wider fender" threads and as I said before, I'm dedicated in having this done for next season. I've got 19x10 et52 in the rear right now which is perfect fitment, but I'd like to fit minimum a 10.5.

Put me down for a set. Although nothing is confirmed yet, it would be good to know who actually is down for a group buy...the only hard part will be figuring out how to ship it to each person lol

Let me confirm with HMS.

The fenders themselves without the rear bumper card is 3 pieces, one being the main flare, one being the flare/door card and the final portion being the flare/side skirt card for the sedan.

I can't confirm that the coupe / sedan rear factory flare is the same as well as the sideskirt but it looks identical. With the help of a good body shop they can integrate the door card/flare into the main flare as one piece to retrofit onto a coupe.

HMS will not ship to a residential address, hence why they didn't want ship their fenders. They will only ship to a US Customs address, once it clears you will pay inbound shipping within the US to you. Downside to this is, many people get raped on shipping charges from HMS to US customs, then customs to you. You will get charged for everything along the way and because it's a private residential customer, you pay full duty/tax. Which ends up being close to $3000-3500 landed.

The way I am trying to do it is, I will be importing them with my work related accounts to my business address. Which saves a lot of tax, shipping and duties. I will be ship the fenders out to you, via UPS commercial account and get charged for actual shipping costs. Packed professionally and with the upmost care.

No matter what, I will acquire these fenders. By buying single order or shipping bulk, I save money and pass the savings and opportunity to the community. (How thoughtful)

I'll get back to you with the coupe fitment.

Also I will prepare another dedicated thread for the HMS Rear wide fender group buy.

Sounds like a plan.

I'm in as well. I can be the Guinea pig for the coupe, and you for the sedan. I would think designing fenders for the coupe would be much simpler since you don't have to deal with the rear door..

Asher4799

If be interested in the buy and I allready run
245/35/19 in front and
275/30/19 in the rear with no rubbing and lowered .75 inch H&R springs so the question is will 315s fit the rear with the kit

gmaschine

That's the spirit.

When it becomes official and the fenders are in our hands. I'm sure we can talk about some of the install process and etc. I doubt they will make a separate kit for the coupe but if the sedan flare works with only molding the card onto the main flare, it's as close as you'll get and you will be the first coupe with them!

gmaschine

I am assuming you are running 19x10?

Here is a sedan running HMS fenders with 20x12.5 with 325's.

This is viper fitment territory.

Phil Chow

Interested to see some sort of price point to see what we're looking at.

AMGPower88

HMS fenders are the way to go, so sick.

Phil Chow

Is HMS willing to give you a discount on the product? What's their lead time?

I've heard they are AWFUL with lead times.

Asher4799

yes 19/10 I cant remember the offset on them but I think plus 50 for the rears

durranic

ooooo count me in I want a set!

ENV²

Very very nice. Looks very lowered RS4ish. The RS4 has always been a favorite of mine because of those flares. This is just an even more bullyish version, I love it.

gmaschine

HMS builds them by hand and are made to order.
Each fender takes 6-7 weeks to make. They aren't mass produced which means the (FRP) fiberglass is fresh and best for fitment.

Mass produced FRP bodykits, lip, etc have good runs in the first dozen or so but the master mold gets tired and that's where you have warping and fitment issues.

Depending on the cost, I am trying to weigh out air freight versus sea freight. With the difference only being a few weeks apart, shipping by air freight will increase exponentially and personally I am still looking for a good body/race shop to install the fenders and custom ordering wheels (6-8 weeks or more)

I'm not in a rush to have them in my hand just yet but please be aware of production times, shipping times and customs delays.

Discount wise, they will give us approx. $100 off each fender kit for meeting the required 5 sets ordered with no discounts on the OEM Black Series liners.

Sounds good, I will add your name to the list on the new thread.

Yes, it does remind me of Audi-type fenders. It's a very aggressive difference from the factory but at a glance, looks very OEM when installed professionally.

With a 19x10j , I would go with a 295 max. 10.5/11 would be better.

If you want to run a 315/325 I would recommend at least a 11j/11.5 with a high offset. Mind you that these fenders are fiberglass and are much more forgiving than metal so you may be able to massage the fiberglass with a heat gun but again you may have to look into the route of custom wheels for running tires that size.

Kriston

For the price of this HMS kit shipped, its better off looking to get a competent shop to build metal flares using the BS fender liners as a guide.


I spoke to my local body shop and they said the job would be around 3K with paint.


PS: I already fit a 19 x 10.5 ET 45 Offset on the rear of my C63 on a 275 without issue. a 285 will also work.

gmaschine

Well with the group buy discount and fair shipping cost. I would hold off on that comment before I have the final total for MBWorld members. I'm literally checking my email every other minute for any updates.

The body shop that quoted you is a great price. But that will vary from each body shop/ race shop. I've seen people on the board pay up to $10,000 to widen their fenders an inch and a half or whatever the factory metal can stretch out to.
I respect that you did the fender widening on stock metal, retained all mounting points for the liner and rear bumper. It's very clean!

But for me and anyone interested in HMS fenders, we are looking for a definite wide body rear fender that has a staggering effect that pushes the flares out further than the stock front fenders. HMS got back to me on the actual size and they are 40-45mm wider than factory. (Shaving and using a heat gun will bow them out closer to 50mm or more) with that being said FRP much easier to repair and because they are externally mounted on the quarter panel, removing them for replacement or repair is easier and more cost effective compared to cutting and shaping metal. I will be cutting and mocking up these fenders myself with the help of an experienced body shop. I am very specific of on how I want them mounted step by step and how I want to seal and rust coat the factory metal underneath.

The main point that sold me on these is the extra sideskirt / rear bumper cards that integrate into the main flare giving these fenders are natural taper down effect into the sideskirt and rear bumper.

Also with the wheel/tire fitment. 19 x 10/10.5j with C63 specific offsets will work 275/285s with certain tire brands on stock metal. But it limits you to a certain ride height and rear passenger/cargo restrictions.

I know many people on this board want to run bigger sizes than that and for those who are force inducted or soon to be (many new kompressor kits are releasing soon and lowering their costs) need the extra width to run massive wheel and tire set ups for optimal traction.

Phil Chow

What offset are they running with the 12.5s?

gmaschine

Here are the specs of the Wolfgang Domanig's C63-RS:

He is using a high disk front to clear the brakes and probably a mid/low disk for the rear. The most aggressive rear on a stock metal on a C63 AMG I've seen is a 10.5 +35.

20 x 9.5 (Probably +40) 245/30/20 (Rolled/semi pulled fronts?)

20 x 12.5 (Probably +25 or lower) 325/25/20 (Modified HMS fenders, you can see where they added more material because the stock HMS flares are a few cm from the gas door and this car is nearly touching. The fenders have to be at least 75mm wide!)





Pre build photo of the rear on stock HMS fenders, you can see how close it is and how hes using every mm of clearance to get away with the most aggressive wheel/tire set up.

Asher4799

you can put me on the list for now I do want to see what it all boils down to price wise. as with a newly blown car I will be having to do the tranny build later this winter while in storage but if funds allow this will be a great option!!!

How's the quality of their work? For $3k with paint that's an amazing deal. I'm from Montreal but would be down to travel to Toronto for $3k + wider rear!

betrezra

I love the look but wonder how the tire wheel offset selection effects performance on the track?

Drag race benefits are clear.

How about the balance on road cours? Is there too wide?
Is there a need to balance front and rear sizes offsets?

gmaschine

Well its up to your preference.

As far as the offset bias, the OE Black Series has quite a gap. Where it runs 19 x 9j +25 front and 9.5j +47 rear.

The only time it may effect anything is running offsets into the negatives which is only for "show car" set ups and in that case the worst thing that can happen is wheel bearings going out.

The most important thing is making sure the rolling diameter of the tire between the front and rear is no more than 5% difference. I use this tool as it comes in handy.
